Josip Juric87 Lightning component re-create canvas element
I have the following situation:
There is a lightning component which shows a canvas html-element, and is used to render a chart. For some reason (which I will not explain here), when I want to redraw the chart, I need to:
1) destroy the existing canvas element,
and
2) create a new canvas element instead.
How can I do this with Lightning Components? Do I need to use the LC Renderer ?

1) Create a new canvas element using the $A.createComponent method
2) Remove the old canvas and add the new canvas to the container element, by setting it's v.body property
Here's the code:
$A.createComponent( 'aura:html', { tag : 'canvas', HTMLAttributes : { width: '300', height: '300' } }, function (el, status, errorMessage) { var container = cmp.find('container'); container.set('v.body', [ el ]); } );
